I dunno man. I mean, you don't think these people could be looking for their friends? Or possibly talking to them? And going through their bags is suspicious too? So if I left university with my textbooks in my bag (accounting for the weight) and I also had a bottle of water in there, I was digging for then I'd automatically be a suspect?

[Original story, posted at 1:11 p.m. Wednesday](CNN) -- Investigators believe they have identified a suspect in the Boston Marathon bombings, a source who has been briefed on the investigation told CNN's John King exclusively.The breakthrough came from analysis of video from a department store near the site of the second explosion. Video from a Boston television station also contributed to the progress, said the source, who declined to be more specific but called it a significant development.Earlier, a federal law enforcement source with firsthand knowledge of the investigation told CNN that a lid to a pressure cooker thought to have been used in the bombings had been found on a roof of a building near the scene.While such clues may move the investigation forward, they did not reveal whether the attack was an act of domestic or foreign terrorism.

I'd say in a case like this nearly everyone is a suspect until the real one is caught. I have no problem with that either.
